After earning his master’s degree in Kinesiology and Exercise Science from Cal Poly in 2015, Scott Williams joined the Mustang women’s soccer staff as a volunteer assistant. He was promoted to assistant coach in 2017 and following a 2021 campaign in which he helped the program capture a share of its first Big West Conference regular season title in eight years, Williams was elevated to associate head coach with the Mustangs in March 2022. Williams is entering his ninth year with the program in 2023 and second as associate head coach.

In addition to his prior duties, Williams is now tasked with scheduling for the Mustangs. Since Williams joined the staff, 21 Cal Poly athletes have received All-Big West accolades and 10 have been named to the Big West All-Freshman Team.

During his playing career with Westmont — which included a run to the quarterfinals of the 2008 NAIA National Championship — Williams was a four-year starter at left back and midfielder. His experience at those positions has led to immediate impacts with the Mustangs.

Cal Poly midfielder Camille Lafaix is a prime example of that as the four-year letterwinner wrapped up an historic career in 2022 by earning her second straight United Soccer Coaches All-West Region First Team selection, becoming just the third player in program history to secure multiple All-West Region First Team selections. She also won Big West Midfielder of the Year for the second consecutive year — the first player in conference history to do so — and became the first player in program history to be named to the Preseason MAC Hermann Trophy Watch List.

Previously, midfielder Kendra Bonsall went on to play for the U.S. at the 2017 World University Games in Taipei, while defender Chelsea Barry won a TopDrawerSoccer National Goal of the Week award.

Also in defense, Robin Mertens earned all-conference first-team honors after Cal Poly limited four Top 15 opponents — Virginia, Stanford, Cal and BYU — to a combined four goals. Emily Hansen, meanwhile, won a Big West Offensive Player of the Week from her midfield spot in 2015.

Barry additionally earned back-to-back NSCAA All-West Region status in 2017 & 2018, following midfielder Megan Abutin’s all-regional nod her senior season.

A native of Albuquerque, New Mexico, Williams graduated with his first degree in Kinesiology from Westmont in 2011 prior to grad school. He is married to Cal Poly head women's tennis coach Ellie Edles Williams and also was an assistant for the Mustang men’s soccer program from 2013-15.
